When your agent uses it

  • Evaluating startups
  • Growth companies through a Sequoia-style lens: founder quality
  • Product-market fit
  • Long-term company building

Example prompts

  • “/sequoia-founder-market”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Evaluate founder and team.
  2. Define market and why now.
  3. Test PMF evidence and distribution path.
  4. Underwrite multi-year company-building potential and round pricing.

What it can do on your machine

Read from SKILL.md and the folder at commit 2844d78. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sequoia Founder Market loads about 485 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~485

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

When To Use

  • Primary documents, product data, user/revenue evidence, or research materials
  • Time horizon, capital structure, and risk constraints
  • Valuation or round pricing if sizing/commitment is requested

Process

  1. Evaluate founder and team.
  2. Define market and why now.
  3. Test PMF evidence and distribution path.
  4. Underwrite multi-year company-building potential and round pricing.
